Anti-Human IgG (Green)

In 1945, Coombs, Mourant and Race described the use of anti-human globulin serum for detecting red cell-bound non-agglutinating antibodies.

When used by recommended techniques, the reagent will cause agglutination (clumping) of red cells, carrying IgG, in the antiglobulin phase of testing. No agglutination usually indicates the absence of IgG.
